jq:tldr:7cf6c

jq: Execute a specific expression (print a colored and formatted json).
$ ${cat filename-json} | jq '.'
try on your machine

This command takes the contents of a JSON file and passes it to the jq command for further processing.

${cat filename-json}: This portion uses the cat command to read and output the contents of the file specified by filename-json. The $ sign is used for variable substitution, so the actual value of filename-json will be substituted here.

|: This is a pipe symbol used to redirect the output of the previous command as input to the next command.

jq '.': This part executes the jq command with a period (.) argument. jq is a command-line JSON processor that allows you to manipulate and extract data from JSON files. The period argument . represents the root object of the JSON, so this command will simply print the entire JSON structure as output without any modification.

In summary, the command reads the contents of a JSON file using cat, passes it to jq for processing, and finally prints the JSON structure as output.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
